In a separate statement, however, Binay’s spokesman, Joey Salgado, said the Vice President "has never sought or asked the president’s endorsement. His candidacy for president as standard bearer of the United Nationalist Alliance (UNA) is not dependent on such endorsement.”

Asked about the support from Aquino’s relatives for a Binay presidency, Trillanes said that is their prerogative, noting that this doesn't necessarily translate to votes from the public.

Trillanes initiated a probe at the Senate on the allegedly overpriced Makati office and parking building, believing that the details unearthed there could be worse than the pork barrel scam.

“Primarily it involved P2 billion that was lost to corruption and it is even bigger than the already scandalous pork barrel scam wherein the three Senators are accused of pocketing more than P100 million. In this case, the Vice President of the Republic is being accused of pocketing at least P2 billion in one project alone,” he said.

Trillanes also believes a Binay presidency may even be worse than that of former President Gloria Macapagal Arroyo.

The senator also downplayed statements that his actions are politically motivated since he has also expressed plans of running for a higher office, saying the hearings will show he did the right thing in initiating a probe.

“Nagsimula po ito sa acts of corruption then later on makikita natin na itong proceeds of corruption kung san napunta,” he said, noting he may look deeper into Binay’s statements of assets, liabilities, and net worth (SALNs).
